Job Title: Cable Engineer – HV (400kV)
Location: (Remote)
Start Date: ASAP (Late April / Early May)
Contract Duration: 13 Months
Engagement: Contract
Position Overview
CMC is supporting a major UK transmission infrastructure scheme requiring senior HV Cable Engineering support for a large-scale cable system.
The successful consultant will join the cable engineering team and take a lead role in supporting the delivery of a 400kV cable system associated with a complex underground route connecting into overhead line interfaces.
Cable Systems / Delivery Responsibilities
- Take a lead role in developing and reviewing cable system design deliverables for a route.
- Review available project scope documentation, design information, and programme inputs to
help define cable engineering responsibilities, identify technical gaps, and raise engineering
queries where required.
- Support the development of cable system designs from feasibility and concept stage through to FEED and detailed design as the project progresses.
- Develop cable design deliverables associated with cable installations, including route layouts, installation considerations, design drawings, technical notes, and engineering reports.
- Prepare and review jointing strategies, joint bay arrangements, and bonding / cross-bonding
designs appropriate for a long-distance 400kV cable system installed predominantly within
tunnel infrastructure.
- Support engineering assessment of cable pulling requirements, installation methodology, shaft
interfaces, and associated tunnel installation constraints.
- Contribute to design activities associated with steelwork support systems, bracketry
arrangements, fixings, and mechanical force considerations related to cable installation within
the tunnel environment.
- Support technical coordination with adjacent disciplines including tunnelling, civils, ventilation,
environmental, and contractor teams to ensure cable designs are practical, coordinated, and
aligned with the wider scheme requirements.
Required Experience
- Minimum 6+ years experience in HV cable system design within power infrastructure projects.
- Demonstrable experience delivering EHV cable systems (ideally 400kV).
- Strong technical capability across cable design, installation, bonding, and jointing.
- Experience on tunnel cable projects or complex underground installations desirable
- Strong understanding of cross-bonding, jointing strategy, and long-route cable design
considerations.
- Experience supporting design across multiple stages
- Strong understanding of National Grid standards and transmission requirements.
- Ability to work within uncertain / evolving scope environments and support engineering
definition.
- Experience working across multi-disciplinary interfaces in complex infrastructure projects
